Our computers are by design offline and our ability to upgrade given our workload is limited, hence we are way behind. I need to do videos capturing using H.264 RTSP stream over UDP sockets and it appears 3.4 or above is the version to use for that. The problem is we have a large C++ system (Windows .NET) with 2.4.3 intertwined throughout a quarter of a million lines of code. If I change our build to point to an installation of 3.4 will it break? Lots of IplImage references...:-(
